No solution. the answer is D.
Cindy is 72 inches long. Imagine it like a right triangle. Her shadow is the base, she is the side, and the distance between her head and the end of the shadow is the diagonal line connecting the two. Use the Pythagorean theorem to find how tall cindy is.
a²+b²=c² a=21, the length of the shadow
b= ? cindy's height
c= 75, the distance from her head to the edge of the shadow
21²+ b²=75²
441 +b² = 5625
-441 -441
------ -------
0 5184
b² = 5184
√b² =√5184
b= 72
hope it helps
Converting decimals into fractions is simple, all you have to do is think about the number, for example .25, if you look at it you realize it's 1/4 of 1, so it's naturally 1/4, you do this with all of them
